My invention relates to condenser systems in general and more specifically to condensers wherein the capacity is adjustable over a given range.

- An object of my invention is to provide certain improvements Yin adjustable condensers -whereby a wide range of capacity may be obtained when used in high power clrcuits.

Another object of my invention is to provide an adjustable high power condenser system whereby relatively coarse adjustments of ca acity may be easily and readily obtainedl Still another object of my invention is to provide an adjustable high power condenser whereby both coarse and fine adjustments of capacity may be easily. and readily obtained.` Other objects of my invention are to provide certain structural features in adjustable condensers, a better understanding of which can be had from the specification following and from the accompanying drawings where- Figure 1 illustrates a part section in side elevation; Fig. 2 shows an end elevation in part section; and Figs. 3 and 4 are side elef vations showing adjustments for different capacity'values. Y Y

In ,condenser systems the capacity depends upon the effective areas of the parts, the dielectric and the separation or spacing of the parts. 'Different adjustments of capacity are imost readily obtained by changing the relal tive area of the parts and this is usually accomplished by moving one 0r more of the y parts comprising the capacity to a position where the adjacent area of the parts is increased or decreased. The movable part is usually moved to a position reserved for such part where the capacity relation is a minimum when a minimum adjustment of capacity isdesired. This space is of no use when adjustments of maximum capacity are made. In the condenser system ofL my invention many disadvantages of other condenser systems are avoided and many advantages are obtained as will appear from the specication following:

Figure 1 of the accompanying drawings illustrates a side elevation of the condenser system of my invention. A plurality of metallic tubes 3, 3a, 3b, 3c, 3d, 3e, 3f, 3g, are supported by member 16 and attached thereto by screws 8 threaded in bushings 5. Tube 3c i's shown in cross-section comprising any suitable metal or alloy thereof. Metallic tubes 2, and 2g slide inside and bear against the interiorwalls of tubes 3 and 3g respectively. lTubes 2g, 2b, 2c, 2e, and 2f have diameters slightl greater than tubes 3a, 3b, 3c, 3d, 3e and 3f, t e interior walls of the former slide over and bear against the latter tubes. The lower ends of tubes 2a, 2b, 20, 2d, 2e and 2f are attached to supporting member 7 by screws 8a. Tubes 2, 2g and 3, 3g have their yupper ends and lower ends respectively so vide a mechanical connection with shaft 11.-

Shaft 11 is supported' by members 11a and 11b, the latter provided with suitable bearings. Members 11a and 11b may be integral' with member 12, the latter being provided with suitable bearings for shafts '9 and 9a. Shaft 9a is similar to shaft 9 and is in like manner mechanically associated with shaft 11 by means of suitable bevel gears 13. Mo tion is transmitted to gears 13, shaft 11 and gears 10 by means of gear 14. Spacing members 16 and 16a support member 6 and themetalli/c tubes associated therewith. Frame member 12 rests upon insulating members 17 which may be mounted on the main framework of the transmitter or apparatus with which the condenser system is to be ems ployed.I A stationary plate member 18 shown in section may be supported from the main framework by insulating members 19. The adjustable tube members and member 6 may be attached to member 12 by means of screws 20 and member 12 in turn positioned to the main framework by screws 21. N

Fig. 2 is an illustration in part section showing an end elevation of the condenser system of my invention. Correspondmg reference characters are employed in all of the drawings. v

Gears 13 are similar to gears 10 and 13 shown in Fig. 1. A rotary motion is transmitted to gears 13 by means of gear 14. Gear 14 is attached to the end of shaft 15, the latter resting in a suitable bearmg provided in member 110. Member 110 may be integral with or in any manner supported from member 12. Members a, 31a and 32a correspond to members 30, 31 and 32 respectively, shown in Fig. 1 previously referred to.

Figs. 3 and 4 of the accompanying drawings illustrate side elevations of t e condenser system of my invention. Stationary plate 18, shown in Figs. 1 and 2, is omitted from Figs. 3 and 4. Fig. 3 shows the position of tubular members 2, 2a, 2b, 2c, 26h26,

- 2f and 2g for maximum capacity setting.

Fig. 4 shows the position of the tubular members for minimum capacity obtainable by means of adjusting mechanism 9, 9a, 10, 11 and 14. Opposite side elevations are illustrated in Figs. 3 and 4.

There is thus provided a condenser having smooth edges and adequate spacings of its elements, with a minimum of corona effect, and therefore adapted for use at high power.

Many combinations of the tubular members are possible to provide a condenser sysl drawings the many possible combinations V*and the advantages may be learned. As an 'en y,

example, suppose that the maximum capacity obtained, when the tubular members are in the position shown in Fig. 3, is greater than that desired. Any or all of tubular members 2a, 2b, 2c, 2d, 2e and 2f may be removed by loosening the screw or screws through member 7 which'holds the respective tubular member or members in place.

By means of adjusting mechanism 9, 10, 11 and 14 the remaining tubular members may be caused to collapse over each other. in

the position lshown in Fig. 4. With certain of tubular members 2a, 2b, 2c, 2d, 2e and 2f removed the minimum capacity will be slightly less than the former capacity value. This slight reduction in the minimum capacity is accounted for by the thickness of the wall of the tubular members removed. The reduction in the maximum capacity obtainable is, however, relatively large. Tubular members 2,' 2a, 2b, 2c, 2d, 2e, 2f and 2g bear against tubular members 3, 3a, 3b, 3c, 3d. 3e. 3f and 3g and the friction may be considerable between the two groups. .j The members may be made of aluminum or other light weight metal. Should it be desired that the minimum capacity value obtainableV by adjusting mechanism 10, 11, 13 and 14 remain the same, although it be also desired to reduce the maximum capacity obtainable b the adjusting mechanism; any or all o tubular members 2a, 2b, 2c, 2d, 2e and 2f may be released from their position to member ,7 when the tubular members are in the position shown in Fig. 4. Now. adjusting mechanlsm 10, 11, 13 and 14 causes the capacity to 1ncrease, the screws being removed from certain of tubular members 2a, 2b, 2c, 2d, 2e and 2f allowing these members to remain in their respective initial positions and not 1niuenced by the downward movement of those members secured by screws to member 7. In like manner any or all of the screws through member 6, serving to attach members 3a, 3b, 3c, 3d, 3e and 3f, may be removed thereby allowing the membersso released to follow the downward movement of any or all of members 2a, 2b, 20, 2d, 2e and 2f. Some of the screws through member 6 and alsoy some o f the screws through member 7 may be removed.

As an example of the iexibility and many combinations, any or all of members 2a, 2b, 2c, 2d, 2e and 2f may be released from member 7 or totally removed from the condenser unit. Likewise any or all of members 3a, 3b, 30, 3d, 3e and 3f may be released from member 6 or totally removed from the condenser unit. By releasing or removing a corresponding number of tubular members from both members 6Y and 7 the maximum capacity value and minimum capacity value obtainable by adjusting mechanism 10, 11, 13 and 14 may be correspondingly lowered.

I realize that many modifications of the condenser system of my invention are possible without departing from the spirit of my invention. Y Such condensers may be connected in series or parallel with other condensers. A plurality of such condensers may be controlled by a single mechanical means. The respective plate members may be other than as illustrated in the accompanying drawings and suitable' mechanical means other than as shown. The parts may be insulated or adequately shielded without departing from my invention.

It is to be further understood that my invention shall not be limited by the fore oing specification or by the accom anying drawings but only by the scope o the appendedv claims.
